We are vastly underestimating the GoPro.
While most of YouTube spends their time sticking these little marvels on drones and floating them over an abandoned theme park or something, these YouTubers are discovering what these cameras are made for: Shooting them out of a cannon.
Sorry, Harold, they aren't made for attaching them to trombones. They're made for shooting them out of a cannon.
I know that you might think that GoPros are better for taking vacation footage or exploring the ocean deep or just getting some cool B-Roll, but trust me, it’s true purpose is shooting them out of a cannon. Just think of it, all the fun of being a circus sideshow freak without any of the danger. It’s the American dream.
YouTubers Sam and Niko explain how it was done in the description.
Potato Cannon we used was built with PVC pipes. We basically went to Home Depot and assembled all the pieces before buying them. It's filled using an air compressor through a nozzle that's tapped into the end of the air chamber. The gun's worked great for the decade or so we've had it!
Pretty cool, but not, like, cannon cool.
